It looks like it is being Skinned by Elv, but Elv doesn't come with skins built-in anymore, which means you somehow have skins still. This could be for a couple of different reasons. Did you completely re-install Elv post-5.0.4, IOW, did you delete the ElvUI folder and install a fresh copy. If not, that could be why it's being skinned. Give me a second to download Ovale and see if my Elv is skinning it.
